Description
Technical Field
The invention relates to a portable dual-interface data carrier comprising a metal sheet, which data carrier is obtainable without much technical effort, in particular without ferrite material. The resulting portable dual interface data carrier is heavier than prior art PVC smart cards and provides a contact type interface on one side, while a non-contact type interface works from both sides of the card. One field of application of such data carriers is the provision of so-called smart cards. The invention also relates to a dual interface module and to a method for providing a portable dual interface data carrier. Furthermore, a data carrier is proposed, which comprises instructions for carrying out the proposed method and for manufacturing a portable dual interface data carrier.
Background
DE 102010005809 a1 shows a portable data carrier comprising a contactless interface made of an antenna coil. Metal layers are discussed in this context.
WO 1993/023826 a1 teaches a portable data carrier in the form of a smart card. This document also discusses metal layers and implicit effects.
It is known to provide so-called dual interface data carriers in the form of smart cards for payment and authentication application scenarios. A smart card is a typical PVC-type credit card that includes some processing components and memory for executing control instructions. In addition, typical smart cards provide dual interfaces for contactless and contact type communications.
Various manufacturing methods are known which laminate the various layers to the card body. However, one problem with known data carriers is that where a metal layer is involved, as discussed in the art, certain interference associated with the antenna may occur.
To overcome this problem, known techniques propose providing slits in the metal layer at the location of the module, so that the metal layer is discontinuous and communication can be made from both sides. It is well known in the art that the slots are very small and need only be of a small enough size to allow data communication. However, there is a disadvantage in that the metal layer becomes unstable, and thus, for example, in daily use, the card body may be broken by an external force. Furthermore, this arrangement requires a special dual interface module which is very costly and can only be realized with great technical effort.
Another solution known in the art, in view of the interference, is to provide a ferrite layer on the back of the metal layer to avoid such interference. However, there is a disadvantage in that such ferrite layers enable the card to communicate wirelessly on only one side of the card. The other side of the card cannot communicate with the radio frequency field due to the shielding caused by the metal layer.
This leads to further problems in that the ferrite layer is costly and the user may find such a card inconvenient since the communication of the antenna is limited to one side of the card.
Disclosure of Invention
It is therefore an object of the present invention to provide a portable data carrier with a dual interface module, which can communicate wirelessly on both sides of a card and which can be realized without much technical effort. It is furthermore an object of the invention to provide such a module and a method of manufacturing a data carrier. It is a further object of the invention to propose a computer program product comprising instructions for carrying out the proposed method.
These objects are achieved by the independent claims. Further advantages are provided by the dependent claims.
The invention therefore proposes a portable dual-interface data carrier comprising a metal layer arranged between at least two plastic layers forming at least a part of a data carrier body, wherein the metal layer comprises a recess of at least the size of a carrier sheet holding an antenna, and the carrier sheet is attached to the plastic layers at the location of the recess and the carrier sheet holding the antenna is embedded in the recess.
Those skilled in the art will recognize that the data carrier presented above may comprise other components, in particular components typical in the art. Such components also relate to the data processing unit and optional security features.
The portable dual interface data carrier of the invention may be provided in the form of a smart card. Typical dimensions of smart cards are illustrated in a number of standards, such as the ANSI/ISO standard. Further, the portable dual-interface data carrier holds a communication module that realizes non-contact type and contact type communications. This communication may be made by a data reader in which the card is inserted and makes physical contact. Furthermore, the antenna provided in the data carrier can be activated and a small current is induced, so that the electronic components of the data carrier can be operated.
The proposed portable dual-interface data carrier is produced primarily using a metal layer and at least two plastic layers, for example PVC, to provide the plastic layers. The specific data carriers can be produced in large quantities using metal and plastic sheet material, which are cut to provide individual metal and plastic laminate parts, which are then laminated to provide the card body. In the context of this document, a layer refers to a layer of a data carrier, wherein a person skilled in the art realizes that larger layers can also be produced as an intermediate step in the production of the individual card bodies.
The metal layer comprises a recess, such that the metal layer appears as a frame provided with recesses. Thus, the recess is surrounded by portions of the metal layer. Accordingly, the recess may be referred to as a window introduced into the metal layer. A window or recess is provided where the final dual interface module and antenna are placed and disposed.
Further, a carrier sheet holding the antenna is also provided. This may be accomplished by attaching the antenna to a carrier sheet or by otherwise forming the sheet and then attaching the antenna to the carrier sheet. In the context of this document, only the final product is illustrated such that the carrier sheet and the antenna form one single unit (i.e. the interface module).
The interface module comprising the carrier sheet and the antenna is produced, which can also be done in a separate step of the card production process. When introducing the carrier sheet and the antenna together into the recess, the dimensions of the recess have to be selected such that the carrier sheet and the antenna fit into such recess. During production, it may also occur that the recess is larger than the carrier foil with the antenna. In this case, an additional filling material is required.
The carrier foil is attached to the plastic layer such that the carrier foil is fixed with or without the antenna to the position of the recess on the plastic layer where the metal layer is to be arranged. This forms an arrangement in which the carrier sheet is enclosed by the recess of the metal layer, with or without the antenna. At least two examples of such composite layers may be provided herein. In a first example, a carrier sheet is attached to a plastic layer holding the antenna; in a second example, the carrier sheet is embedded in the recess in liquid form and subsequently cured so that the antenna can be arranged on top of the carrier sheet. In a second example, the carrier sheet is attached to the plastic layer separately, wherein in the first example the carrier sheet is attached to the plastic layer together with the antenna. As a result of this process, the carrier sheet holding the antenna is finally attached to the plastic layer.
The end product is a dual interface data carrier comprising a metal layer between at least two plastic layers and wherein the carrier foil is introduced together with the antenna into a recess of the metal layer. This may be referred to as a so-called sandwich arrangement, wherein the metal layer comprising the antenna module is embedded between two plastic layers.
According to one aspect of the invention, the at least two plastic layers comprise at least one transparent sheet and/or at least one opaque sheet, or both sheets are opaque. This has the advantage that a plastic layer can be produced which provides a further visual effect, in particular, for example, a transparent plastic layer can be provided as a top layer and a further opaque layer can be provided on the rear side of the data carrier. The plastic layer may comprise further layers, in particular a plurality of plastic layers may be arranged above and below the metal layer.
According to another aspect of the invention, the thickness of the carrier sheet is at least the same as the thickness of the metal layer. This has the advantage that the carrier foil can be embedded in the metal layer in a closed manner. Therefore, even in the case of including the carrier sheet and the antenna, the metal layers have substantially the same thickness. In this way, the composite layer can be processed in a manner known in the art without the need to process variations in thickness.
According to another aspect of the invention, the thickness of the carrier sheet is greater than the thickness of the metal layer. This has the advantage that the antenna layer is closer to the dual interface module and the metal layer can remain in the middle of the card construction.
According to another aspect of the invention, the size of the carrier sheet holding the antenna does not exceed the size of the recess. This has the advantage that the carrier sheet can be completely inserted into the recess without further steps having to be performed. Thus, the carrier sheet remains substantially the same size as the recess. The carrier sheet may also be smaller than the recesses, as will be shown below.
According to another aspect of the invention, the size of the carrier sheet holding the antenna is smaller than the size of the recess, and the gap between the recess and the plastic layer carrying the antenna is filled with a filling material. This has the advantage that even in the case of carrier sheets which are smaller than the recesses due to manufacturing tolerances, standard manufacturing procedures can be carried out and the gap formed between the interface module and the recess can be filled to provide a stable arrangement.
According to another aspect of the invention, the layers are laminated to form the body of the data carrier. This has the advantage that existing tools can be reused and that the metal layer can be treated as a known composite layer even in the case where the metal layer comprises a carrier sheet and an antenna.
According to another aspect of the invention, the layers are bonded using an ultraviolet adhesive to form the body of the data carrier. This has the advantage that no heat has to be applied and therefore the structure of the data carrier is not damaged. The ultraviolet adhesive is a specific adhesive cured using ultraviolet rays.
According to a further aspect of the invention, the antenna is attached to other components of the data carrier. This has the advantage that the antenna can be used to provide a dual interface and also to provide further contact type components. In order to provide a monolithic dual interface data carrier, known components that may be involved in the proposed interface module are to be attached.
According to another aspect of the invention, the data carrier carries further components for forming a contact-type interface. This has the advantage that also components can be introduced which are able to interact with the card reader, whereby prefabricated contact-type accessories can be combined with the structure of the invention.
According to another aspect of the invention, the antenna forms a contactless interface to the data carrier. This has the advantage that the data carrier can be coupled to other devices. Thereby wireless communication is formed and existing card readers can also be reused. Also, communication can be made on both sides of the card.
According to another aspect of the invention, the carrier sheet is attached to the plastic layer by means of an adhesive layer. This has the advantage that the plastic layer or carrier sheet can provide an adhesive layer which can be formed and arranged between the carrier sheet and the plastic layer, so that easily implementable manufacturing steps can be carried out.
According to another aspect of the invention, the carrier sheet is provided in a solidified liquid form. This has the advantage that the recesses can be filled with a material which subsequently forms the carrier sheet. The liquid material may be cured immediately after it is embedded in the recess, and the antenna may be attached subsequently.
The object of the invention is also achieved by a dual interface module to be embedded in a data carrier as described in one of the above aspects. The dual interface module comprises at least a carrier sheet and an antenna, which are dimensioned to be insertable into a recess of a data carrier.
The object of the invention is also achieved by a method for providing a portable dual interface data carrier, comprising the steps of: forming a metal layer including a recess having a size of at least a size of a carrier sheet holding the antenna; attaching a carrier sheet holding an antenna to the plastic layer at the location of the recess; and embedding a carrier sheet holding the antenna in the recess, thereby forming at least a part of the body of the data carrier.
Those skilled in the art will appreciate that the above method steps may be performed iteratively and/or in a different order. Furthermore, substeps may also be involved. For example, the carrier sheet holding the antenna may be embedded in the recess by a single process step, or such process steps may be subdivided, i.e. the material forming the carrier sheet is first introduced into the recess and then the antenna is arranged on top of the carrier sheet.
The object of the invention is also achieved by a computer program product holding instructions for executing the proposed method.
It is an advantage of the invention that the proposed dual interface data carrier comprises a data module which holds structural features, such as a carrier sheet and an antenna, which are dimensioned such that they can be embedded in a recess. Furthermore, the dual-interface data carrier can be manufactured using the proposed method, which, in turn, involves the proposed method steps in the formation of the structural features. Hence, the procedural aspects mentioned here may mean that structural features which are part of the proposed data carrier as well as other structural or functional features of the proposed data carrier can be implemented using the proposed method.

Detailed Description
Fig. 1 shows the general structure of a data carrier according to the invention, wherein a first plastic layer 1 is provided on the top of the card and a second plastic layer 3 is provided on the back of the card. Between the layers 1 and 3, a further layer, namely a metal layer 2, is provided. As can be seen from fig. 1, the overall structure is a so-called sandwich structure, in which a metal layer 2 is embedded between two plastic layers 1, 3.
The arrangement shown in fig. 1 may also comprise a PVC sheet 1 and/or a PVC sheet 3, which may be opaque and made of coloured PVC. The PVC sheets 1 and/or 3 may also be coated with a thin metal film to create a full foil layer effect. The laminate structure of fig. 1 may be formed by laminating or embedding more opaque or transparent PVC layers to produce a standard smart card having a thickness of about 760 and 840 microns in compliance with ISO, ANSI, CQM requirements.
The arrangement of layers may also be a sandwich structure sandwiched between PVC layers, which may also be transparent. Thus, additional PVC layers may be disposed above layer 1 and below layer 3, which may provide a protective coating.
As can be seen from the left and right side of fig. 1, the metal layer 2 is visible from both sides, so that when cutting the card body out of the respective sheet, the metal edge can be seen from at least one side of the card body. Thus, smart cards include an embedded metal layer, so that after the card is cut from the finished laminate sheet, a metal edge is revealed on the side of the card body. The metal edge of at least one side of the card is visible during use and provides stability to the card edge and also creates a high quality design that communicates out of the card.
In summary, the overall structure shown in FIG. 1 includes two metal edges that are visible to the user.
Fig. 2 shows a metal layer 2 with recesses 4 arranged in a frame-like structure. The metal layers 2 may be provided using large metal sheets and may be divided to form the individual metal layers 2. The window structure of the recess as shown in fig. 2 is only an example and not a limitation. However, such a window-like size is preferred.
Fig. 3 shows an interface module to be embedded in the metal layer 2. The interface module comprises a carrier sheet 5 with an antenna 6. For connecting the antenna 6 with other components of the data carrier, a connection unit 7 is provided, which can be used for joining the antenna with other contact-type components.
The connection unit 7 may be used for connection with an interface module as shown in fig. 5, for example the interface module 10. The carrier sheet should have the thickness of the metal layer 2. A larger sheet may be used to provide the carrier sheet 5 from which the individual carrier sheets are separated. Such splitting may be performed by stamping, laser cutting or water jet cutting. The same applies to other layers to be separated, for example plastic layers.
Fig. 4 shows the gap 8 between the recess 4 and the carrier sheet 5. Such gaps may be filled with a liquid filling material and subsequently cured. Furthermore, an adhesive may be used to introduce the cover sheet 1. Finally, the composite layers can be bonded together using temperature and pressure (e.g., applied during lamination). In addition, ultraviolet adhesives may be used instead of or in addition to. In this way, no heat is applied to the individual layers without lamination being completed.
The dual interface module 10 is then introduced into a card 9 which can serve as the proposed data carrier. This arrangement is shown in figure 5.
In general, the recess 4 of the metal layer 2 may be arranged such that the antenna 5 is a single component comprising the carrier sheet 5 and the antenna 6. In this way, the composite antenna sheet 5 is formed. Likewise, the recess 4 may also be filled with material to form a sheet carrying the antenna. This liquid material may be liquid PVC and, when cured, the antenna 6 may be applied including the adhesive 7. Furthermore, a plastic overlay 1 may be attached to the composite structure.
The invention has the advantages that: the contactless data transfer function of the card can be realized on both sides of the card, and furthermore, the use of expensive ferrite is not required.
Fig. 6 shows a metal sheet 2A for providing the metal layer 2. The metal sheet 2A may comprise a stamped recess 4 and in a further step the metal layer 4 is stamped out of the metal sheet 2A. In this way, a large number of metal layers can be produced. A similar process may be used to provide the plastic layer. The layer to be punched out is indicated with reference numeral 11.
Fig. 7 shows a flow chart of a method for providing a portable dual interface data carrier, the method comprising the steps of: forming 100 a metal layer 2 comprising a recess 4, the recess 4 having at least the size of the carrier sheet 5 holding the antenna 6; attaching 101 a carrier sheet 5 holding an antenna 6 to the plastic layers 1, 3 at the location of the recess 4; and embedding a carrier sheet 5 holding an antenna 6 in the recess 4, thereby forming at least a part of the body of the data carrier.
As mentioned above, the proposed method may further comprise sub-steps, which may be performed iteratively and/or in a different order, among other things.
